About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5241023017. Listed at 24 retailers as of November 5, 2026, with prices from $10,147 to $20,527, a $10,380 spread on the same certified stone. NZ Jewellers lists it at $20,527. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
